Construction method for high-mixing-content steel slag micro-powder and cement composite concrete pavement
The invention discloses a construction method for a high-mixing-content steel slag micro-powder and cement composite concrete pavement. The construction method comprises the following steps: S1, mounting of a template: putting the template onto a base layer according to a pay-off position, and driving steel chisels into the base layer at two sides of the template to fix the template; S2, mixing and transporting of large-mixing-amount steel slag micro-powder and cement concrete: a step of blending 180-200 parts by weight of cement, 180-200 parts by weight of steel slag micro-powder, 1100-1150 parts by weight of machine-made sand, 700-800 parts by weight of broken stone and 140-160 parts by weight of water through a concrete stirrer, and after completion of stirring, conveying an obtained mixture into a construction site; S3, paving and compacting by vibration; S4, surface shaping and repairing; S5, joint construction; and S6, curing and engraving. According to the invention, a scientific raw material ratio is obtained through strict tests, so addition of high-mixing-content steel slag micro-powder can be realized in the pavement paving process.
本发明公开了一种大掺量钢渣微粉水泥复合砼路面施工方法，包括如下步骤：S1、安装模板：按放线位置将模板放在基层上，两侧用钢钎打入基层来固定模板；S2、大掺量钢渣微粉水泥砼的拌和与运输：将水泥、钢渣微粉、碎石、机制砂和水采用混凝土搅拌机进行拌和，其中，水泥180‑200重量份，钢渣微粉180‑200重量份，机制砂1100‑1150重量份，碎石700‑800重量份，水140‑160重量份，搅拌完成后，运至施工现场；S3、摊铺振实；S4、整修表面；S5、接缝施工；S6、养生与刻纹。本发明通过严格的试验得到了科学的原料配比，使得在路面铺筑过程中能够实现大掺量的钢渣微粉的添加。
